- Abstract
- In this study, dynamic analysis and model tests were performed for the installation of a flare tower using two floating cranes. The dynamic analysis system is developed based on the multibody equations of motion by considering external forces such as wave, wind, current, mooring, and wire rope forces. Numerical integrator for solving equations and static analysis for finding the initial position and orientation are provided in the system. The user interface including modeling function, scenario setting function, and result analysis tool is provided. The dynamic analysis was validated by the model tests for the same installation equipment and procedure. The installation is to turn-over the flare tower by controlling boom angle and wire rope length using two different sized floating cranes. We compared the both results of the dynamic analysis and the model tests about the 6-DOF motions of the floating cranes and the flare tower, and the tension of the wire ropes and the mooring lines. ? 2019 by the International Society of Offshore and Polar Engineers (ISOPE).
